The Lake of Hrid, located in Prokletije National Park, stands out with its picturesqueness and specifity of ecosystem.  This „mountain eye“ is located some 18km from Plav, at 1970 meter altitude, that is, between Big and Small Hrid.  Its maximum depth is 5 meters.  The lake is very interesting looking from scientific, business-touristic and educational point of view.

Lake of Hrid nature reserve may also be described as a juncture of diverse natural ecosystems, starting from the lake itself to unique mixed compounds of endemic-relict pines and specific botanical and fauna species in the nearby surrounding areas. The lake itself is rich in biodiversity and accordingly provides natural habitat for over 245 types of algae with 75 of them being registered in Montenegro for the first time.  Additionally, numerous species co–habiting in this lake include countless number of amphibian sorts, with Alpine Newt (Ichthyosaura alpestris) being an exceptional amphibian type living in this particular area.  Bogicevica Mountain is most probably the only location where you may see black salamander and this place is quite close the Lake.

Due to frequent lake water penetration from their inflow, it somehow seems to be vanishing. Only certain water quantity has been accumulated because the water itself flows away thus forming a stream which again, with its downwards flowing forms Hrid River. Clear and very archaic ingredients of Macedonian Pine (Pinus peuce) forests can be found in Hrid River basin.

Volušnica Nature reserve is an area with specific botanical characteristics. Harsh climate conditions in high mountain area nurtured specific plants with impressive number of relict, endemic-relict and rare plant types.

The reserve stretches from the Vezirova brada slopes all the way of to peaks of Maja Potkajs (2071), to Donje and Gornje Krošnje, Ljubokuča, Očnjaka, Oble glava to the highest peaks of Karanfil. This chain separates magnificent meadows Grbaja and Ropojana.  It is exceptionally diverse and impressive mountainous and high-mountainous area with stone pastures, mountainous meadows, rocks and cliffs.
